Ryan Christoffel, also at 9to5Mac:

There are two key features that are part of iOS 18.2, but aren’t yet ready for the Mac:

1. Genmoji
2. Mail app redesign

Genmoji are an especially unfortunate omission, as they’re available on both iPhone and iPad with iOS and iPadOS 18.2. Meanwhile the Mail app redesign is currently iPhone-exclusive, so it’s missing from both the Mac and iPad in these next software updates.

The omission of Genmoji creation in MacOS 15.2, and the omission of the new AI inbox categorization features in Mail on both iPad and Mac, aren’t surprises — they weren’t in any of the betas for these .2 OS updates. But it is a weirdly glaring omission. Apple itself started promoting screenshots of the Apple Intelligence inbox categorization in Mail for Mac back in October, when the .1 OS updates shipped with the initial round of Apple Intelligence features.

I am reliably informed that the new Mail categorization features are coming soon to iPad and Mac, which I suspect means in the .3 updates. But the first .3 betas aren’t out yet.
